Abstract (en)
The present invention is directed to a biomass-derived plastic laminated molding shaped in bottle(s), which, when hermetically sealed, do not deform under load and have their high-impact property enhanced, and to a manufacturing method of the same. The biomass-derived plastic laminated molding is characterized in that a preform is molded out of plastic in laminated shape so as to have at least one of layers composed of biomass-derived plastic by 25 wt% or over and the remaining layers composed of polyolefin resins, and that the plastic preform undergoes annealing where it is exposed to blown air heated to raise temperature at a rate of 5 to 20 °C/min from the room temperature up to 85 to 100 °C at which the preform is left for 3 to 10 minutes, and thereafter, the blown air is gradually cooled down at the rate of 10 to 15 °C/min
